Dear Robyn,

I think you are in serious trouble. I laughed my arse off at your last post about the mice. I hear you still haven’t caught the two that were hiding in your bedroom. This doesn’t bode well because I did some research into mice and there are some alarming statistics for what “two” mice of opposite gender are capable of in their lifetimes… Did you realise:

.

  1. Mice are a bit like, ahem… rabbits… in that they like do house maintenance. (Particularly screwing in lightbulbs*)
  2. Mice have litters of 10 pups on average after a 20 day gestation period
  3. 25 days after the pups are born and have been weaned the females are ready for lightbulb duty again
  4. 50 days after pups are born they themselves are old enough to go to Uni and get up to no good with their own lightbulbs and the other student mice their own age.

This makes for rather an alarming possibility. A population explosion in your bedroom! If we presume that your two mice are a boy called Bertie and a girl called Beatrice and that all litters created are 50% split male and female, I imagine your mice population might unfold something like this over the coming year – remembering that with each generation of pups there is a growing number of partners available:

(And in case you are wondering – yes, I did actually do the math for this! I am not guessing. You can download my calculations and check them with this .xls mice breeding )

Day 0 (The day you lost your two mice)
Our darling little pair, Bertie and Beatrice notice the lights aren’t working in your bedroom and decide to screw in a lightbulb* for you. (Aww, such thoughful guests!)

Day 20
Bertie and Beatrice become the proud parents of 10 skirming “pinkies” called Boris, Benjamin, Bucko, Baldrick, Bartie, Britta, Bronhilda, Berta, Betsy and Brenna (aka “Team 2”)

Whatdaya know? That bloody lightbulb blew again. Bertie and Beatrice to the rescue.

Population 22

Day 70

Population 2’812

Day 250
Teams 2-6 launch Squeak-Fest in the linen cupboard to mark the opening of a great new nightclub and visit the hospital (the bathroom medicine cabinet) afterwards to visit Teams 10 – 15 and see their 1’500 little ones (Teams 42-47)
Population 4’312

Population 9’572

Day 295

Population 12’072

Day 300
Teams 38-47 find the mirror ball in the walk in closet and start a new night club called “Ball” which requires the installation of 1’250 lights, while Team 73 introduce 6’250 future club goer to the world.
Population 18’322

Day 315

Population 66’132

Day 360
A quiet one. Teams 2-8 create 350 new kiddies
Population 66’482

Day 365
Mondo Mayhem. 25’000 pups born to Teams 38-57 making the total population 91’482!!!

So there you have it. If you don’t manage to catch those mice by the end of the year you will have 91’482 little stinky inhabitants in your room!

Of course there is something else to consider here. Generally speaking critters from the same close family don’t mate otherwise you get inbreeding (well, except in some countries….). So either this means a good thing – you won’t have 91,000+ mice in your room, or a bad one – you will and they all have 2 heads, five arms and seven tails!

I wish you and the cat A LOT OF GOOD LUCK!

Morgan 🙂

Q: How many mice does it take to screw in a lightbulb?
A: Two. But I don’t know how you get them in there!

**
I named the teams in generations:

Team  1              = Bertie and Beatrice
Teams 2-9        = Their own children (litters of 10)
Teams 10-37   = Their grand children (litters of 50)
Teams 38-72   = Their great-grand children (litters of 250)
And so on…. up to Team 113 (litter of 6’250)

Some teams did not produce offspring as they were born less than 70 before the end of the year.

    Hi Morgan,

    In this case you better come down now, as otherwise there will not be any room for you later in the year with all the baby mice.

    The upside of course, is that I wouldn’t need to buy catfood for the cat for the rest of her natural life 😉

    Cheers
    Robyn
